    Existing deletion solutions have solely depended on a timing mechanism, set and controlled by a central location. The sender of the text message had no control, or knowledge of the text message existence, after it has been sent. Existing systems do not make the mobile sender aware of the successful completion of the deletion of the sent text message. The life cycle of the mobile sender's text message is left to the strength, or weakness of a central system in use, enterprise policy, the receiving end user device, and or the action of message receiver. Transmission of discrete messages, while being secure in the transient state, are left vulnerable when received and stored on the receiver's mobile device.
  • [0004]
    Accordingly, what is desired is a method for enabling message senders, such as SMS message senders, to have the capability to set, at their own convenience, the life cycle of their sent messages, once the remote devices has received the messages.
  • FIELD OF THE INVENTION
  • [0005]
    The present invention generally relates to methods and a message delivery system, and more particularly, to methods and a message delivery system for remotely deleting short message service messages stored on the remote mobile communication device, by initiating a delete command, or setting a message lifespan when creating a SMS message, from a sender mobile communication device.
  • BACKGROUND OF INVENTION
  • [0006]
    Concerns about exposure of what was assumed to be confidential exchanges of information, has been the subject of debates aired over the media. It has become obvious that information, once transmitted, may be viewed by third parties along the message communication pathway and by others, the message receiver may choose to disclose to. Many forms of message and communication encryption strategies address the communication pathway disclosure issue, but the end user receiver disclosure still exists. In the mobile space, this problem is magnified several times, due to the obvious transient nature of end users. For example, the sender of a text message has no control or knowledge of the text message's existence, after it has been sent. The life cycle of the mobile sender's text message is left to the message recipient, the strength, or weakness of system in use, and/or enterprise policy. This scenario adds to the problem of information leakage, which remains an issue even if the line of transmission is secure.
  • [0007]
    Elaborate security schemes are available to ensure confidentiality is ensured. However, the mobile recipient is not considered to be a member of the group of links, in the security chain, that may pose as a concern. For example, a sender transmits an encrypted text message to a mobile receiver, who successfully open and reads the message. This discrete message is unreadable to everyone except the sender and recipient, thus maintaining confidentiality. However, if the receiver decides, on his own, to disclose the content of the message, later to a third party, the sender receiver confidentiality will be compromised.
  • [0008]
    Therefore, improvements for a mobile communication and a method for managing sent SMS messages, by a message sender, or owner, are needed in the industry to address the aforementioned deficiency.
  • BRIEF SUMMARY OF THE INVENTION
  • [0009]
    Embodiments of the present invention provide techniques that enable a sender, using a mobile device, to delete, at any time, a sent text message residing on a receiver's mobile device. After sending a text message to the receiver, the sender will be notified of the opening and reading of the text message located on the receiver's mobile device. With this alert, the sender may chose to delete the remotely located text message. Alternatively, the sender may set a relative time and send a message that will automatically get deleted, at the relative amount of time, after it is opened and read, or at the relative amount of time after it arrives on the device.
